Abstract

A lithium-ion battery includes a positive electrode, a negative electrode, and a battery case. The positive electrode includes a positive current collector, a first material of the form Li1−xMO2, where M is a metal, and a second material including carbon. The negative electrode includes a negative current collector, a third material including a lithium titanate material, and a fourth material including carbon. The battery case includes titanium and at least partially surrounds the positive and negative electrodes.
